The rule as a mapping for the translation of a rectangle is (x, y) → (x – 2, y + 7). Which describes this translation?

The x-coordinate changes from x to x − 2, so every point moves 2 units to the left. The y-coordinate changes from y to y + 7, so every point moves 7 units up; this is a translation 2 units left and 7 units up.
